A fence is an important part of any outdoor space. It defines boundaries, provides security, and enhances aesthetics. When selecting a fence, durability is a top consideration – you want it to stand up well in all weather conditions with minimal maintenance required. Considering Acorn Fencing Aldershot ensures that you’re investing in a high-quality fence that will reliably fulfill these essential functions for years to come.
Concrete is emerging as a popular fencing material due to its strength and resilience. Concrete fences are constructed using precast concrete panels or poured concrete posts and rails. The concrete mix often contains reinforcing steel rebar rods for enhanced structral stability.
Benefits of concrete fencing include:
- Highly durable and impact resistant
- Long lifespan with little maintenance
- Structurally strong – can withstand high winds
- Resistant to moisture damage and decay
- Low risk of damage from lawn equipment
- Fireproof and termite resistant
Concrete is an inorganic material that does not rot, warp, or burn. With proper installation, a concrete fence can last for decades with minimal upkeep required.
The Impact of UK Weather on Fencing Materials
To understand why concrete makes a good fencing choice for the UK, it’s helpful to first look at how typical UK weather impacts various fencing materials. The UK climate is generally temperate but highly variable by region. Here are some defining weather factors:
- Rainfall: The UK is known for high annual rainfall and moisture levels. England averages 797mm annually. Wet weather is distributed evenly throughout the year.
- Temperature: England sees average summer highs of 21°C and average winter lows of 2°C. There are occasional heatwaves and cold snaps ranging from -10°C to 35°C.
- Wind: Average wind speeds range from 10-25 km/h through most regions. Coastal areas and hilltops experience the highest regular wind intensity. Periodic windstorms bring gusts ≥ 100 km/h.
Exposure to heavy rain, moisture, temperature swings, and high winds can impact fence durability in different ways.
Impacts on Traditional Fencing Materials
Common fencing materials used across the UK include wooden planks or slats, PVC vinyl panels, wrought iron bars or mesh, and chain link. Most are vulnerable in some way:
- Wood: With frequent rain and dampness, wooden fences often warp, crack, and rot over time. Fungi and mould growth require regular cleaning treatments. High winds can loosen joints and topple sections.
- PVC/Vinyl: Vinyl stands up well to moisture but can become brittle and cracked in very cold temperatures. High winds sometimes cause fastener failure resulting in detached panels.
- Wrought Iron/Metal: Exposed metal is prone to rusting and corrosion, requiring frequent repainting. Bar or wire mesh fences collect debris and moss. Wind load can bend or detach posts.
Without proper treatment and maintenance, most common fencing deteriorates faster in the cool, wet UK climate.
Advantages of Concrete Fencing
Concrete makes an exceptional fencing material because it stands up well to all types of weather exposure with minimal damage or decay.
Durability
Concrete resists deterioration from all of the elements – including UK rain. Key advantages:
- Moisture Resistance – Concrete is an inorganic material that does not rot, mold, or warp when wet. It does not require weather-proofing treatments or moisture barriers.
- Freeze-Thaw Stable – Concrete’s compressive strength withstands repeated freeze/thaw cycles without developing cracks or spalling damage.
- No Decomposition – Concrete does not decompose – it retains its structural strength and appearance long-term without decay or fading.
Made from rock, sand, and water – concrete is already hardened against the effects of wet weather. The UK’s frequent rain does not degrade concrete fencing like it does wood or metal over time.
Strength & Stability
In addition to moisture resistance, concrete fences provide exceptional stability and wind resistance:
- Withstands Strong Winds – Concrete’s structural integrity and embedded footings resist overturning or detachment in high winds better than vinyl or metal fencing.
- Impact Resistant – Concrete fences withstand accidental impacts from lawn equipment or falling tree limbs without compromise. No dents, cracks, or breakage.
Careful engineering allows precast concrete fences to meet UK building code wind load requirements up to Category 3 storms (55-105 mph gusts). Properly installed, concrete fences stand up well to the strongest anticipated UK weather events.
Low Maintenance
One of the biggest advantages of concrete fencing is reduced maintenance:
- No Upkeep – Concrete fences do not require periodic sealing, staining, cleaning or repainting like wood or metal to maintain appearance and prevent deterioration.
- Cost Savings – While concrete has a higher initial cost, the savings on maintenance supplies and labor over decades result in a lower lifetime cost than wood or vinyl.
Set it and forget it. With concrete privacy fencing, homeowners can enjoy decades of uninterrupted performance without ongoing maintenance headaches.
Concrete provides a smart long-term investment given reduced operating costs from a total ownership view.
Considerations for Installing Concrete Fences
To achieve optimal results from precast concrete fencing, proper installation is key. Here are best practices to follow:
Proper Installation
Carefully following concrete fence installation guidelines ensures your fence can withstand UK weather exposure over the long-term:
- Foundation Prep – Concrete posts should be embedded into concrete footers below the frost line to prevent shifting. Soil conditions factor into depth and width needs.
- Level Alignment – Use string lines and bubble levels when positioning posts to ensure panels sit straight and even as intended for optimal structural strength.
Skipping steps compromises overall stability and wind resistance. Professional installation is strongly recommended to avoid issues.
Suitable Concrete Fence Styles
Concrete fence panels come in different styles – both solid and partially open slatted designs. Choose panels best suited for wind resistance:
- Solid Privacy Panels – Completely enclosed flat panels provide maximum wind resistance. They also block more sound.
- Partially Open Panels – Slatted or decorative concrete panels serve well in most UK wind zones but may allow some air flow-through in coastal applications.
Discuss options with your supplier depending on the typical wind speeds in your UK location.
Surface treatments like integrated color, exposed aggregate, acid-etching, or graffiti-proof coatings provide additional weathering protection from the elements while enhancing visual appeal. Ask your concrete contractor which treatments could benefit local conditions.
Environmental Considerations
Beyond weather resilience, concrete’s overall sustainability should be weighed:
- Recyclability – At end of lifespan, 100% of concrete can be crushed and recycled as drainage aggregate for roads or landscaping. It does not end up in landfills.
- Low Carbon Footprint – Modern concrete mixes use less cement and incorporate recycled materials like fly ash and slag to reduce associated CO2 emissions.
- Responsible Production – UK concrete companies utilize responsible manufacturing processes. Many hold ISO certifications for environmental practices.
Compared to disposal and replacement of rotted wood or bent metal fences decade after decade, concrete provides a more sustainable long-term solution in line with eco-values. Responsible production, recyclability, and extremely long functional lifespans are key advantages to consider alongside weather resilience.
Properly manufactured and professionally installed precast concrete delivers durability with minimal lifetime environmental impact.
Frequently Asked Questions
Will concrete fences crack in extreme UK temperature changes?
Properly engineered concrete can withstand temperature fluctuations from -15°C to 40°C without damage. Gradual temperature changes do not negatively impact concrete.
How does concrete compare to wood fences in terms of maintenance?
Concrete fences require virtually no maintenance over decades of use. Wooden fences require frequent sealing, stain refreshing, mold removal, and eventual replacement due to extensive rotting.
